Subject: Remove an unnecessary allocation.
X-Git-Url: https://git.librecmc.org/?p=oweals%2Fopkg-lede.git;a=commitdiff_plain;h=f8980c8d1dd162031290602cb3d494d617ff51ba

Remove an unnecessary allocation.

According to SUS3:
If the value of n is zero on a call to snprintf(), nothing shall be written, the number of bytes that would have been written had n been sufficiently large excluding the terminating null shall be returned, and s may be a null pointer.
